MOP WRINGER.

Application filed December 15, 1926. Serial No. 154,892.

My invention relates to an improvement in mop wringers shown in the accompanying drawings and more particularly described in the following specification and claims.

This invention relates to the type of mop wringer in which the wringing mechanism includes a jointed frame with one portion adapted for attachment to a pail,the other portion being pivoted to the first named portion with a pair of rollers respectively journalled in said fixed and stationary portions of the frame so that upon rocking the swinging portion of the frame the rollers may be separated to admit a mop between the rollers which when closed upon the mop and manually rotated will operate to express water from the latter.

One of the objects of the present invention is to so construct the swinging frame thatthe operator may bear upon the latter with his knee, thereby exerting pressure through the rollers upon the mop while manually rotating one of the rollers to express water therefrom,a concave depression being provided in the frame that the knee of the operator may not slip OK the frame when pressure is applied.

A further object of the invention is to construct the swinging portion of the frame with one or more arms of relatively different length to provide for gradational leverage,both arms having a concave formation to receive the operators knee that the latter may not slip from the frame when exerting pressure upon the mop through the rollers while manually turning the latter to express water therefrom. Y

A further object of this invention is to provide means for guiding the mop so that the threads of the mop may not become entangled with the shaft of the roller and the supporting frame, the purpose of the guides being to protect the mop from becoming entangled with the shaft while turning the roller.

A further object of the invention is to provide means whereby the pressure of the knee of the operator upon the swinging frame may be exerted without danger of tipping the pail and spilling its contents.

A further object of the invention is to pro vide means whereby the wringer may be secured to the wall of a pail without danger of the wringer becoming loosened in use.

WVith' the foregoing and other objects in view which will appear as the description proceeds, the invention further resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes may be made in the precise embodiment of the invention herein disclosed without departing from the spirit of the same. 7

In the drawings accompanying this specification and forming a part thereof:

Figure 1 is a plan view of a mop wringer secured to the wall of a pall and showing the swinging frame open to receive a mop between its rollers.

Figure 2 is a side elevation of the device shown in Figure 1 with parts broken away and in section.

Figure 3 is a fragmentary view with parts broken away and in section, showing the swinging frame with the rollers journalled therein closed upon a mop as when expressing water therefrom.

Figure 4 is a plan view of a modification comprising a detachable frame secured to a pail,-indicated in dotted lineswith the wringing rollers in open position to receive a mop.

Figure 5 is a cross-sectional elevation taken on or about line 55 of Figure 4:-

Figure 6 is a sectional elevation of the device mounted upon a pail-indicated in dotted lines-showing the wringing rollers in closed relation as when expressing water from the mop.

Figure 7 is a fragmentary plan and sectional view taken on or about line 77 of Figure 5, showing a fragment of the pail between the depending lugs of the frame and secured thereto through the adjustment of a thumb-screw.

Figure 8 is a fragmentary sectional view taken on or about line 8-8 of Figure 4.

Referring now to the letters of reference placed upon the drawings:

A denotes a pail upon which is mounted a wringer 13 including a frame consisting of two hinged members C and D. The member (3 is fixedly .secured to the pail while the member D is pivoted at F to the fixed frame. Join-nailed in the fixed frame 0 is a corrugated roller E, and journalled in the swinging frame D is a corrugated roller G, the shaft G of which projects beyond the wall of the pail and is fitted with a crank arm G 111g rearwardly from the arc-shaped portionhD of the swinging. frame is an arm D liaringaconeave depression D on its upper also overlaps the front of the face to acconnnodate the knee of the oper ator.

Adjacent to the arm D and integral'witli the arc-shaped portion of the swinging frame is a relativel shorter arm D which I also forxnedi with as cup-75h aped depression lll on its uppenface to-reoeivetlteknee'of the operator. HH are guide members to direct the mop away fromlthe ernds-of-the corrugated rollers that the: threads of: the mop may not: beeonie ent angled. between the ends of the roller and the hearings-support ing its shaft.

In the modification shown in Figures 4 and 5 these guides consist of: an; extension C of the stationary frame; pmjeetingi below the corr ugated: rollem-thestationary frame roller to direct thethreadsof the map away fromdtlie ends of the roller when expresmgx water from theunop;

In the modification shown in Figures 4 and 5 the fixed frame is provided: with staggered lugs- G G? one: of which is provided with a tlllllllbOf'SBt-l screw 6 which when adjusted willenga; themvall of the pail bending the sameshghtly that it may impinge against the lugs-asashown in1Fig*. ure7, thereby insuring a: rigidmountingeiof the frame uponthe pail, I isadugrpnojecting from the wall at. the hottmnof the pail to prevent the pail tipping; under the prese sure of the operators knee whenrinthe position: shown in Figure 3.

Havingindicated llllfl%\7fifitli partsby. reference letters, the construction: and operation of the device willbe readily understood When it is a desired. to express water from the mop, the swinging'fmmeistiltedtmthe position indicated in Figures 1,22, and 5 that the mop may be inserted" between the corrugated rollers. The swinging frame is then shi ftedto the position-indicated iniFi gures 3and 6, the operator nesting his knee upon-either ofthe ext-ensions-of'the swinging frame dependent upon the pm'ssum' he desires to exert. 'l he cmnli annrGr'is' then manually rotated, forcingtlre water from the mop through the action of the oorrngatedrollers. 7

It will be seen that the concave formation of the: arms D' D on which theyoperator rests his knee willinsure-againstslippage of the knee of the operator when applying pressure to the swinging frame. This feature of the-invention.has through use been found of great advantage, as without the depI'O'SSlOIlllt is difiicmt tollnaintainthe knee uponthe projections while applying. pressuresimultaneously with the rotationofrthe wringing: rollers.

By providing extensions of relatively differeht.lengths-,thepressure applied maybe graduated todneet the requirements of the mop. 7
